CROSS-REFERENCE TO RELATED APPLICATIONS

The present application claims priority to U.S. Provisional Application No. 60/608,168, filed Sep. 8, 2004, entitled “METHODS, SYSTEMS, AND KEY FOB APPARATUSES FOR FACILITATING HANDS FREE MOBILE COMMUNICATIONS FROM WITHIN AN AUTOMOTIVE VEHICLE.”

FIELD OF THE INVENTION

The present invention relates to hands free mobile or cellular communication in automotive vehicles. More particularly, but not exclusively, the present invention relates to methods, systems, and apparatuses for facilitating hands free mobile communications from within automotive vehicles.

BACKGROUND OF THE INVENTION

The use of cellular phones in automobiles has increased significantly. However, historically it has been difficult and/or expensive for automobile manufacturers to provide in-vehicle “hands free” operation of cellular phone handsets. Due to mechanical and electrical differences among cellular phone designs, automobile manufacturers have not been successful in providing users a standard handset cradle capable of accommodating cellular phones from a wide variety of manufacturers.

Manufacturers have had some limited success in supporting hands free operation of cellular phones. However, the support is limited to specific handsets produced by specific handset manufacturers and supporting a single communications system technology, such as Advance Mobile Phone Service (AMPS). Meanwhile, there is increasing pressure to mandate the use of “hands free” technology in automobiles for use of cellular phones.

One communications system, Global System for Mobile communication (GSM), has become a dominant cellular technology in the world market. A key component of GSM technology is the Subscriber Identity Module (SIM). The primary role of the SIM is to authenticate a user on the GSM network and facilitate billing. SIMs are issued by GSM network service providers to subscribers. Subscribers can move their SIMs, in the form of SIM cards, from one GSM phone to another GSM phone, thus transferring their identity.

It is with respect to these and other considerations that the present invention has been made.

SUMMARY OF THE INVENTION

Embodiments of the present invention provide methods, systems and key fob apparatuses for facilitating hands free mobile communications from within an automotive vehicle. Mobile phone technology is built into automotive vehicles and integrated with in vehicle microphones, radio, antenna, and speakers to support hands free operation and communication. A means for receiving a SIM of a variety of subscribers, such as a slot and/or an ignition switch operatively associated with a SIM reader, is also provided. Thus, when subscribers enter any automotive vehicle equipped with an integrated mobile phone, such as a GSM phone, they simply plug in their SIM, for example into the SIM slot, and are able to use the integrated mobile phone as their own.

One embodiment of the present invention is a method for facilitating hands free mobile communications from within an automotive vehicle. The method involves provisioning mobile phone technology within the automotive vehicle and providing a means, such as a SIM slot or ignition switch, for receiving a SIM, such as a SIM card, of a subscriber within the automotive vehicle. The method also involves providing a SIM reader for reading data from the SIM of the subscriber and upon receiving the SIM, reading data from the SIM of the subscriber to authenticate the subscriber on a mobile network thereby activating the provisioned mobile phone technology within the automotive vehicle. Provisioning the mobile phone technology within the automotive vehicle involves integrating a mobile phone with an antenna, a radio, a microphone, and a speaker of the automotive vehicle whereby hands free operation of the mobile phone and communication are facilitated.

Another embodiment of the present invention is an apparatus for facilitating hands free wireless communication from within an automotive vehicle equipped with an integrated mobile phone. The apparatus includes a key fob with a housing and a SIM associated with the housing. The SIM is operative to identify a subscriber to a mobile telephone network when interfaced with the mobile telephone network. The apparatus may further include a key integrated with the key fob and operatively associated with the SIM. The key is operative to initiate the start of an engine of the automotive vehicle and interface the SIM with a mobile telephone, such as a GSM phone, integrated with the automotive vehicle. Thus, when the key is inserted into an ignition switch operatively associated with a SIM reader, the SIM identifies a subscriber to the mobile telephone network.

Still another embodiment of the present invention is a system for facilitating hands free wireless communication from within an automotive vehicle. The system includes a SIM operative to identify a subscriber to a mobile telephone network and a mobile telephone integrated into the automotive vehicle. The mobile telephone is operative to interface with the mobile telephone network. The system also includes a means for interfacing the SIM with the mobile telephone integrated into the automotive vehicle thereby activating the mobile phone and authenticating the subscriber with the mobile telephone network.
